Foss EFT Tube (650b) 27.5x1.95-2.25 AV

The new FOSS EFT tube system is being produced from a thermoplastic
elastomer compound, which not only makes it especially lightweight but
also puncture-proof.

Our EFT is a highly polymerized un-vulcanized rubber composite. When
punctured, the material forms an air-tight seal around the nail or
glass, retarding the leak speed, giving riders extra time to react.

With a density of only 0.88 g/cc,our EFT is 30% lighter than traditional tubes which can have densities up to 1.3 g/cc.

Made from modified thermoplastic elastomer compounds(TPE),our EFT can be
recycled with other TPE products,thus minimizing waste and protecting
the environment.
